PROJECT TITLE :

Efficient closed-form estimators for multistatic sonar localization

ABSTRACT:

This paper addresses the multistatic sonar localization drawback using time measurements solely or with bearings in the presence of Gaussian transmitter positions, receiver positions, and propagation speed variations. We tend to develop efficient algebraic solutions to the present nonlinear estimation drawback through parameter transformation and multistage processing. Each things of known and unknown statistical distribution of the propagation speed are thought-about. Analysis supports their performance in reaching the hybrid Cramer-Rao lower bound (CRLB) over the little error region.
